 it is frequently quite destructive. Spraying with the 

 arsenites is probably as promising as any general 

 remedy in these eases, though the experience of nur- 

 serymen has shown that on young nursery stock the 

 insect may advantageously be destroyed by hiring 

 bovs to crush the larva' within their cases.
